refers to specific purebred poultry that hatch with distinct visual differences between males and females, allowing for immediate gender identification without invasive methods like vent sexing. Unlike "sex-links," which are first-generation hybrids, autosexing breeds "breed true," meaning their offspring will also possess these same identifiable traits. Core Mechanism: The Barring Gene
Because the barring gene is carried on the Z chromosome, a male chick receives two "doses" ( BBcap B cap B autosexing
Breeds like the Rhodebar, Welbar, and Wybar follow similar naming and genetic conventions. Autosexing vs. Sex-Linked Hybrids refers to specific purebred poultry that hatch with
Known as "German Kennhuhns," these show very distinct down colors at hatch. Autosexing vs
Result from crossing two different breeds (e.g., a Rhode Island Red rooster and a Delaware hen). Their offspring will not breed true; if you mate two sex-links, the next generation will lose the predictable color markers. Performance Benefits
Several breeds have been developed—often by crossing a barred breed with a non-barred breed and then stabilizing the line—to achieve these results:
